Do you remember Netzero from the 90s? They had a "free" dialup service that was funded by ads. It was designed for win98 users. There was a hack available to remove the ugly banner that popped up during dialup on the "warez" websites lol. None of them worked. Companies like that sell whatever's available to whoever pays.

How much of the stuff on eBay do you think came from trash or garage sales? People sell stuff...ask ThatOnePrivacyGuy

Most of the "free" dialup services back then attempted to require the use of a "dialer" apps that would pass an obfuscated version of your password to the Windows PPP stack. There were some debug features built into Windows that would allow you to log the obfuscated password. Once you did that, you could use it directly without the dialer. This was known as "DUNing" and worked pretty well for a while.
